Shingle Roof Warranty Guide

Shingle roof warranties in Palm Beach County, Florida typically include two components: a manufacturer's material warranty covering defects in the shingles themselves, and a contractor workmanship warranty covering the quality of installation. Understanding what each warranty covers — and what it excludes — helps homeowners protect their investment and understand their rights when problems arise.

Manufacturer's Shingle Warranty Explained

Most architectural shingles come with a manufacturer's limited warranty ranging from 25 to 50 years, with some premium products offering a lifetime limited warranty. However, these warranties are prorated — meaning the coverage decreases over time. In the early years, manufacturers typically provide full material replacement; in later years, only a fraction of the replacement cost is covered. Algae warranties (typically 10–15 years) cover discoloration from algae growth on warranted algae-resistant shingles.

Contractor Workmanship Warranty

The workmanship warranty covers the quality of the installation itself — leaks or failures caused by installation errors rather than material defects. Ranger Roofing provides a workmanship warranty on all shingle roof installations throughout Palm Beach County. The duration varies by project; we provide full warranty documentation with every completed installation.

What Voids a Shingle Warranty in Florida

• Installation by an unlicensed contractor

• Improper ventilation in the attic (causes premature shingle failure)

• Installation over existing shingles (not permitted by most manufacturers)

• Damage caused by storm events (typically excluded from material warranty but covered by insurance)

• Unauthorized modifications or penetrations added after installation
